NCRs against mpi-defaults 1.17

[Erich Eickmeyer]

Hello all!

Last week, Olivier Gayout was in #ubuntu-devel and asked for a NCR of 
netgen against mpi-defaults 1.17. Well, it turned out that wasn't the 
only package that needed it, as we found a ton of rdepends that needed 
rebuilding against the new mpi-defaults. Ultimately, several ended up 
completely FTBFS on GCC-14 [1] and a handful only on armhf [2]. The vast 
majority are upstream issues in Debian and I have found the upstream 
bugs, but there are a few standouts.

  - hdf5 is fixed in Debian, but will need a substantial merge.
  - scalapack says it's fixed in Debian, but I've deduced that if they 
were to rebuild it would fail again. Upstream's recommendation is to not 
use GCC-14 [3]. Obviously not an option.
  - Miriam España Acebal fixed the armhf problem with form, I sponsored 
(Thanks Miriam!).
  - mumps is actually an mpi bug, still working on what the Debian bug 
is there, needs a new bug filed.
  - netcdf is our bug, nothing upstream in Debian. Needs more investigation.
  - r-cran-metamix is removed from Debian, needs to be removed from 
Ubuntu, no rdeps other than a metapackage, bug already filed [4] .

That said, this turned into a much larger project than I thought it 
would be, and all that's left is the FTBFS issues. If anyone can 
join-in, please do!
